Asking for 'experience at X place' implies only timespan or also details of the experience it self?

In the application form of a internship one of the fields states Experience at (current work place) with no additional information. The field allows for a more than one-line answer and I am not pretty sure if they are asking just for how long have I been working in this place or, in addition, how my experience has been or a description of the things I’ve done while working at the current place.
